Description

一种旋风分离装置及清洁设备Cyclone separation device and cleaning equipment 技术领域technical field
本发明涉及旋风分离技术领域,尤其涉及了一种旋风分离装置及清洁设备。The invention relates to the technical field of cyclone separation, in particular to a cyclone separation device and cleaning equipment.
背景技术Background technique
具有旋风分离器的清洁设备如真空吸尘器是已知现有技术。一般情况下,旋风式真空吸尘器中,其中携带脏物和灰尘的空气经有切向入口进入第一旋风分离器,通过离心力作用将脏物分离再收集腔内,较清洁的空气穿出该收集腔室进入第二旋风分离器,相比第一旋风分离器可分离更细微的脏物和灰尘等微粒。现有第二旋风分离器主要包括旋风分离筒和溢流筒,它们之间留有适当的空间,让含尘气体在两者之间形成旋转气流带,质量大的颗粒在离心力作用下甩向筒壁,气体形成涡流,向压力较低的内筒流动,最后从溢流筒向上排出,起除尘净化作用。Cleaning equipment such as vacuum cleaners with cyclones are known in the prior art. Under normal circumstances, in a cyclone vacuum cleaner, the air carrying dirt and dust enters the first cyclone separator through a tangential inlet, and the dirt is separated by centrifugal force and then collected into the cavity, and the cleaner air passes through the collection chamber. The chamber enters the second cyclone, which can separate finer particles such as dirt and dust than the first cyclone. The existing second cyclone separator mainly includes a cyclone separation cylinder and an overflow cylinder, and there is an appropriate space between them, so that the dust-laden gas can form a rotating airflow belt between the two, and the particles with large mass are thrown towards the centrifugal force under the action of centrifugal force. On the cylinder wall, the gas forms a vortex, flows to the inner cylinder with lower pressure, and finally discharges upward from the overflow cylinder, which plays the role of dust removal and purification.

However, the inventors found that although the existing secondary cyclone separation can effectively improve the separation effect of dust and air, the cyclone separation cylinder of the downstream cyclone separation assembly accumulates a large amount of dust, and there is also dust accumulation outside the overflow cylinder, mainly due to the separation The remaining dust is difficult to be discharged to the dust outlet only by its own gravity, resulting in a large amount of accumulation in the outer cylinder of cyclone separation, and there is also the possibility of backmixing and diffusion escaping to the overflow cylinder. Therefore, how to discharge and separate in time and quickly It is a technical problem existing in the prior art to send the latter particles to the dust outlet.

本发明人分析后认为是:气流在回转时,在忽略重力影响的情况下,气流中的微粒只受到一个筒壁给予的支持力(合力),因为存在回转运动,这个支持力(合力)必然会分解成一个垂直于回转轴线的向心力(第一分力)和另外一个第二分力,为了保证合力的分解平衡,这个第一分力和第二分力一定存在于支持力(合力)的两侧,才能保证合力的分解平衡,本发明通过曲线通道使得回转气流的向心力方向由原本垂直于回转轴线的方向发生偏摆后与所述旋风分离筒筒壁支持力方向之间形成一个朝上的夹角,即所述回转气流的向心力(第一分力)方向改变至所述旋风分离筒筒壁支持力方向的侧上方,则跟向心力(第一分力)平衡的第二分力的方向被调整到朝下,有利于让微粒在这个朝下分力(第二分力)的牵引下流出至旋风分离筒的排尘口之外。如此,本发明旋风分离器通过所述切向风道及曲线通道的相结合能够有效地将分离后的微粒及时快速的排出至排尘口之外,不仅解决了上述背景技术中所描述的技术难题,而且避免了堆积的微粒造成返混与扩散的可能性,同时保证旋风分离筒处于无微粒堆积的干净状态下有助于提高分离净化效果以及使用寿命。After analysis, the inventor believes that: when the airflow is rotating, under the condition of ignoring the influence of gravity, the particles in the airflow are only subjected to a supporting force (resultant force) given by one cylinder wall, and because of the rotational motion, this supporting force (resultant force) must be It will be decomposed into a centripetal force (first component force) perpendicular to the rotation axis and another second component force. In order to ensure the decomposition and balance of the resultant force, the first component force and the second component force must exist in the supporting force (resultant force). Only on both sides can the decomposition balance of the resultant force be ensured. In the present invention, the direction of the centripetal force of the rotating airflow is deflected from the direction originally perpendicular to the rotating axis and the direction of the supporting force on the wall of the cyclone separation cylinder is formed through the curved channel. The included angle, that is, the direction of the centripetal force (first component force) of the rotating airflow changes to the side above the direction of the support force of the cyclone wall, then the second component force balanced with the centripetal force (first component force) The direction is adjusted downward, which is beneficial to let the particles flow out of the dust outlet of the cyclone separator under the traction of this downward component force (the second component force). In this way, the cyclone separator of the present invention can effectively discharge the separated particles to the dust outlet in a timely and rapid manner through the combination of the tangential air channel and the curved channel, which not only solves the technical problems described in the above background technology It also avoids the possibility of backmixing and diffusion caused by accumulated particles, and at the same time ensures that the cyclone separator is in a clean state without particle accumulation, which helps to improve the separation and purification effect and service life.
如果没有曲线通道,回转气流的向心力(第一分力F1’)的方向不会改变,即处于筒壁支持力方向的下方,那根据合力的分解平衡,则与该第一分力F1’平衡的第二分力F2’就会一直朝上,则微粒就没有排出旋风分离筒的任何作用力,无法排出的微粒就只能堆积在旋风分离筒的筒壁上。If there is no curved channel, the direction of the centripetal force (the first component force F1') of the rotating airflow will not change, that is, it is below the direction of the supporting force of the cylinder wall, then according to the decomposition balance of the resultant force, it is balanced with the first component force F1' The second component force F2' of the cyclone will always face upward, and the particles will not have any force to discharge the cyclone separation cylinder, and the particles that cannot be discharged can only accumulate on the cylinder wall of the cyclone separation cylinder.

实施例1Example 1
针对现有技术所存在的技术问题,请参考图1-19,本发明提供了一种旋风分离装置,其包括上游旋风分离组件100和下游旋风分离组件200,所述上游旋风分离组件100和下游旋风分离组件200通过导风路径连通;所述下游旋风分离组件200包括旋风器支架210及设置在所述旋风器支架210上的至少一旋风器环220,每一所述旋风器环220包括多个旋风分离器300。In view of the technical problems existing in the prior art, please refer to FIGS. 1-19, the present invention provides a cyclone separation device, which includes an upstream cyclone separation assembly 100 and a downstream cyclone separation assembly 200, the upstream cyclone separation assembly 100 and the downstream The cyclone separation assembly 200 is communicated through a wind guide path; the downstream cyclone separation assembly 200 includes a cyclone support 210 and at least one cyclone ring 220 disposed on the cyclone support 210, each of the cyclone rings 220 includes multiple cyclone separator 300.
具体地,请参考图3-13,每一所述旋风分离器300,其包括:Specifically, please refer to FIGS. 3-13 , each of the cyclones 300 includes:
旋风分离筒310,其上部侧边连通有切向风道320;所述切向风道320具有气流引导路径,且与所述旋风分离筒310的侧边相切以将带有微粒的空气引导成与切向风道320方向一致的气流后再切向进入所述旋风分离筒310形成回转气流,即旋风气流;The upper side of the cyclone separation cylinder 310 is connected with a tangential air duct 320; the tangential air duct 320 has an air flow guiding path and is tangent to the side of the cyclone separation cylinder 310 to guide the air with particles After forming the airflow in the same direction as the tangential air duct 320, it enters the cyclone separator 310 tangentially to form a rotating airflow, that is, a cyclone airflow;
曲线通道330,其设置在所述旋风分离筒310的上部内,且与所述切向风道320相通,所述曲线通道330的螺旋升角λ大于所述旋风分离筒310的倒锥筒312的半锥角a,使得所述回转气流进入所述曲线通道330后所述回转气流的向心力方向发生改变至所述旋风分离筒310筒壁支持力方向的侧上方。The curved channel 330 is arranged in the upper part of the cyclone separation drum 310 and communicated with the tangential air channel 320 , and the helix angle λ of the curved channel 330 is greater than the inverted cone 312 of the cyclone separation drum 310 The half-cone angle a of , makes the direction of the centripetal force of the swirling airflow change to the upper side of the direction of the supporting force of the cyclone wall 310 after the swirling airflow enters the curved channel 330 .
所述旋风分离筒310包括圆柱筒311和倒锥筒312;所述圆柱筒311底部与所述倒锥筒312的上部连接相通,所述圆柱筒311上部为敞口端3111,便于装配溢流筒340;所述圆柱筒311侧边开设有开口3112,所述切向风道320连通所述开口3112实现所述切向风道320与所述圆柱筒311的相切连接;所述倒锥筒312上部的宽口端3121连接所述圆柱筒311的下部以连通所述圆柱筒311和倒锥筒312,所述倒锥筒312下部的窄口端3122为排尘口,用于允许分离后的微粒经所述排尘口排出。The cyclone separation cylinder 310 includes a cylindrical cylinder 311 and an inverted cone cylinder 312; the bottom of the cylindrical cylinder 311 is connected to the upper part of the inverted cone cylinder 312, and the upper part of the cylindrical cylinder 311 is an open end 3111, which is convenient for assembly and overflow cylinder 340; an opening 3112 is formed on the side of the cylindrical cylinder 311, and the tangential air duct 320 communicates with the opening 3112 to realize the tangential connection between the tangential air duct 320 and the cylindrical cylinder 311; the inverted cone The wide end 3121 of the upper part of the cylinder 312 is connected to the lower part of the cylindrical cylinder 311 to communicate the cylindrical cylinder 311 and the inverted cone 312, and the narrow end 3122 of the lower part of the inverted cone 312 is a dust outlet for allowing separation The latter particles are discharged through the dust outlet.
所述旋风分离器300还包括溢流筒340,其同轴线350设置在所述旋风分离筒310的上部内作为排气出口,以允许分离后的气流离开所述旋风分离筒310,所述溢流筒340从所述圆柱筒311的敞口端3111插入且与所述圆柱筒311同轴线350设置。The cyclone separator 300 further includes an overflow tube 340, the coaxial line 350 of which is arranged in the upper part of the cyclone separation tube 310 as an exhaust outlet to allow the separated airflow to leave the cyclone separation tube 310, the The overflow tube 340 is inserted from the open end 3111 of the cylindrical tube 311 and is arranged on a coaxial line 350 with the cylindrical tube 311 .
需要说明的是,当高速回转的气流和物质速度V和回转半径R的比值V²/R远远大于重力加速度g的情况下,花粉级的微粒所受向心力M*V²/R远远大于物质本身的重力Mg,为了便于分析,故忽略微粒重力的影响。It should be noted that when the ratio V²/R of the high-speed rotating airflow and material velocity V to the radius of gyration R is much greater than the gravitational acceleration g, the centripetal force M*V²/R on the pollen-level particles is much greater than that of the material itself. The gravity of Mg, in order to facilitate the analysis, the effect of particle gravity is ignored.
气流在回转时,在忽略重力影响的情况下,气流中的微粒只受到一个筒壁给予的支持力N(合力,F N),因为存在回转运动,这个支持力N必然会分解成一个垂直于回转轴线350的向心力(第一分力,F 1、F 1’),该第一分力用于维持微粒做高速回转运动,该第一分力的方向为垂直指向气流回转中心轴线350,由于支持力F N垂直于倒锥筒312筒壁,根据力的矢量分解,为维持支持力F N和向心力F 1、F 1’的矢量平衡,另外一个分力(第二分力)必定和向心力F 1、F 1’分别跨居在支持力N的两侧,才能保证合力的分解平衡。 When the airflow is rotating, ignoring the influence of gravity, the particles in the airflow are only subjected to the supporting force N (resultant force, F N ) given by one cylinder wall. Because of the rotating motion, this supporting force N must be decomposed into a vertical The centripetal force of the rotation axis 350 (the first component force, F 1 , F 1 ′), the first component force is used to maintain the high-speed rotation of the particles, and the direction of the first component force is perpendicular to the airflow rotation center axis 350, because The support force F N is perpendicular to the wall of the inverted cone 312, and according to the vector decomposition of the force, in order to maintain the vector balance between the support force F N and the centripetal forces F 1 and F 1 ′, the other component force (the second force component) must be the same as the centripetal force. Only when F 1 and F 1 ' are located on both sides of the supporting force N can ensure the decomposition and balance of the resultant force.
请参考图7,在没有所述曲线通道330之前,某一处回转气流的回转平面A垂直于所述旋风分离筒110轴线350,其向心力(分力F 1’)的方向不会改变,即指向回转平面A圆心且处于筒壁支持力F N方向的下方,向心力F 1’与筒壁支持力F N的夹角为θ,那根据合力的分解平衡,则与该分力F 1’平衡的分力F 2’就会一直朝上,可以理解的是,在此受力情况下,则高速回转的微粒就没有任何朝下排出所述倒锥筒312的牵引动力,即没有排出旋风分离筒310的任何作用力,那么无法排出的微粒就只能堆积在旋风分离筒310的筒壁上。 Please refer to FIG. 7 , before the curved channel 330 , the rotating plane A of the rotating airflow at a certain place is perpendicular to the axis 350 of the cyclone separator 110 , and the direction of the centripetal force (component force F 1 ′) will not change, that is, Pointing to the center of the rotation plane A and below the direction of the cylinder wall supporting force F N , the angle between the centripetal force F 1 ' and the cylinder wall supporting force F N is θ, then according to the decomposition balance of the resultant force, it is balanced with the component force F 1 ' The component force F 2 ' will always be upward, and it can be understood that under this force, the particles rotating at high speed will not have any traction power to discharge the inverted cone 312 downward, that is, there will be no cyclone separation. No matter the force of the cylinder 310, the particles that cannot be discharged can only accumulate on the cylinder wall of the cyclone separation cylinder 310.
请参考图8、9,当设置有所述曲线通道330时,当气流从具有气流引导路径的切向风道320的切向出风口325流出后沿所述圆柱筒311筒壁形成回转气流,由于所述切向出风口325对应所述曲线通道330的入道口331,则当形成回转气流之后,回转气流即进入具有向心力改向作用的所述曲线通道330,由于所述曲线通道330以及其螺旋升角λ大于所述倒锥筒312的半锥角α的限制,使得所述回转气流从所述曲线通道330的出道口332进入所述倒锥筒312后,回转气流的向心力方向由原本垂直于回转轴线350的方向发生偏摆,与所述倒锥筒312筒壁的支持力方向之间形成一个朝上的夹角。可以理解的是,通过设置改向通道,在第三维空间内提供一个与上述没有设置改向通道的向心力F 1’方向呈朝上夹角(此夹角为螺旋升角λ)的气流回转平面B,即把回转气流中的微粒的向心力F 1方向改变到所述倒锥筒312筒壁提供的支持力F N的上方,同样的,根据力学受力分析原理:回转气流中的微粒仍然只受到一个来自于所述倒锥筒312筒壁提供的支持力F N(合力),该支持力F N的第一个分力即为维持微粒做高速回转运动的向心力F 1,在上述改向通道的作用下,此向心力F 1方向由垂直指向气流回转中心轴线350的方向变更到第三维空间内那个方向呈朝上夹角的气流回转平面内,由于支持力F N垂直于所述倒锥筒312筒壁,根据力的矢量分解,为维持合力支持力F N和向心力F 1的矢量平衡,另外一个分力F 2必定和向心力F 1分别跨居在合力支持力F N的两侧;如此,故当回转气流在所述改向通道之后,回转气流中的微粒受到的另一个分力F 2方向是朝下的,可以理解的是,在此受力情况下,高速回转的微粒在一个朝下分力的牵引下朝下运动,故从气流分离出来的微粒必然能排出所述倒锥筒312至排尘口外。 Please refer to FIGS. 8 and 9 , when the curved channel 330 is provided, when the airflow flows out from the tangential air outlet 325 of the tangential air duct 320 with the airflow guide path, a rotating airflow is formed along the wall of the cylindrical cylinder 311 , Since the tangential air outlet 325 corresponds to the inlet 331 of the curved channel 330 , after the swirling airflow is formed, the swirling airflow enters the curved channel 330 with the effect of centripetal force redirection. The helix angle λ is greater than the limit of the half cone angle α of the inverted cone 312 , so that after the rotating airflow enters the inverted cone 312 from the outlet 332 of the curved channel 330 , the direction of the centripetal force of the rotating airflow changes from the original one. The deflection occurs in the direction perpendicular to the rotation axis 350 , forming an upward included angle with the direction of the supporting force of the cylindrical wall of the inverted cone 312 . It can be understood that, by setting the redirection channel, an airflow rotation plane is provided in the third-dimensional space with an upward angle (the angle is the helix angle λ) with the direction of the centripetal force F 1 ' without the redirection channel. B, that is to change the direction of the centripetal force F 1 of the particles in the swirling airflow to the top of the support force F N provided by the wall of the inverted cone 312. Similarly, according to the principle of mechanical force analysis: the particles in the swirling airflow are still only Received a support force F N (resultant force) provided by the wall of the inverted cone 312, the first component of the support force F N is the centripetal force F 1 that maintains the high-speed rotary motion of the particles. Under the action of the channel, the direction of the centripetal force F 1 is changed from the direction perpendicular to the center axis 350 of the airflow rotation to the airflow rotation plane with an upward angle in the third dimension space, because the supporting force F N is perpendicular to the inverted cone. The cylinder wall of the cylinder 312 is decomposed according to the vector of the force, in order to maintain the vector balance of the resultant support force F N and the centripetal force F 1 , another component force F 2 must and the centripetal force F 1 straddle the two sides of the resultant force support force F N respectively; In this way, when the swirling airflow is behind the redirecting passage, the direction of another component force F 2 that the particles in the swirling airflow are subjected to is downward. The traction of a downward component force moves downward, so the particles separated from the airflow must be discharged from the inverted cone 312 to the outside of the dust discharge port.
如此,本发明旋风分离器300通过所述切向风道320及改向通道的相结合能够有效地将分离后的微粒及时快速的排出至排尘口之外,不仅解决了上述背景技术中所描述的技术难题,而且避免了堆积的微粒造成返混与扩散的可能性,同时保证旋风分离筒310处于无微粒堆积的干净状态下有助于提高分离净化效果以及使用寿命。若没有所述切向风道320,则当所述改向通道导程小于一个导程不仅无法形成旋风而且存在气流未分离而经溢流筒340被直接吸走的可能性,当所述改向通道大于一个导程甚至更多的时候也仅仅是起到了形成旋风的作用,对于快速排出堆积的微粒没有起到任何的牵引作用。In this way, the cyclone separator 300 of the present invention can effectively and quickly discharge the separated particles to the outside of the dust outlet through the combination of the tangential air channel 320 and the redirecting channel, which not only solves the problems in the above-mentioned background art. The technical problems described above are avoided, and the possibility of back-mixing and diffusion caused by accumulated particles is avoided, and at the same time, ensuring that the cyclone separation drum 310 is in a clean state without particle accumulation is helpful to improve the separation and purification effect and service life. Without the tangential air channel 320, when the lead of the redirecting channel is less than one lead, not only a cyclone cannot be formed, but also there is a possibility that the airflow is not separated and is directly sucked away through the overflow tube 340. When the direction of the channel is larger than one lead or even more, it only plays the role of forming a cyclone, and does not have any traction effect on the rapid discharge of accumulated particles.
请参考图4、10,所述切向风道320包括下壁321及与所述下壁321两侧分别连接的外侧壁322和内侧壁323,通过两侧壁(内侧壁323和外侧壁322)与下壁321形成具有一定距离的风道槽324,即气流引导路径,以将带有微粒的空气引导成与切向风道320方向一致的气流。所述风道槽324一端与所述圆柱筒311侧边的开口3112连接作为切向出风口325,所述切向风道320的外侧壁322连接于所述开口3112的一边,内侧壁323连接于所述开口3112的另一边且与所述圆柱筒311侧边相切,以将与所述切向风道320方向一致的气流再切向进入所述旋风分离筒310的圆柱筒311形成回转气流。Please refer to FIGS. 4 and 10 , the tangential air duct 320 includes a lower wall 321 and an outer side wall 322 and an inner side wall 323 respectively connected to both sides of the lower wall 321 . ) and the lower wall 321 to form an air duct groove 324 with a certain distance, that is, an airflow guide path, so as to guide the air with particles into an airflow consistent with the direction of the tangential air duct 320 . One end of the air duct groove 324 is connected with the opening 3112 on the side of the cylindrical cylinder 311 as a tangential air outlet 325. The outer side wall 322 of the tangential air duct 320 is connected to one side of the opening 3112, and the inner side wall 323 is connected to On the other side of the opening 3112 and tangent to the side of the cylindrical tube 311 , the air flow in the same direction as the tangential air duct 320 tangentially enters the cylindrical tube 311 of the cyclone separation tube 310 to form a rotation airflow.
请参考图4-6,所述曲线通道330的入道口331对应所述切向风道320的切向出风口325,可以理解为所述入道口331位于所述切向风道320的延伸区域内。进一步地,所述切向风道320的高度对应所述曲线通道330的宽度设置;所述切向风道320的宽度对应所述溢流筒340与所述旋风分离筒310之间的间距设置。此处的对应可以理解为相等或者略小。如此设计,主要是满足所述切向风道320的切向出风口325与所述曲线通道330直接对应连通,降低气流不必要的旋转路径而造成能量损耗。Referring to FIGS. 4-6 , the inlet 331 of the curved channel 330 corresponds to the tangential air outlet 325 of the tangential air duct 320 . It can be understood that the inlet 331 is located in the extension area of the tangential air duct 320 Inside. Further, the height of the tangential air channel 320 is set corresponding to the width of the curved channel 330 ; the width of the tangential air channel 320 is set corresponding to the distance between the overflow tube 340 and the cyclone separation tube 310 . The correspondence here can be understood as equal or slightly smaller. Such a design mainly satisfies that the tangential air outlet 325 of the tangential air duct 320 is directly connected to the curved channel 330, thereby reducing the energy loss caused by the unnecessary rotational path of the airflow.
作为一种实施方式,所述切向风道320的外侧壁322可以设置为平面式侧壁,其相切于所述旋风分离筒310的圆柱筒311侧边,内侧壁323可以设置为平面式侧壁或曲面式侧壁。作为另一种实施方式,所述切向风道320的外侧壁322可以设置为曲面式侧壁,其相切于所述旋风分离筒310的圆柱筒311侧边,内侧壁323为平面式侧壁或曲面式侧壁。As an embodiment, the outer side wall 322 of the tangential air duct 320 can be set as a planar side wall, which is tangent to the side of the cylindrical cylinder 311 of the cyclone separation cylinder 310, and the inner side wall 323 can be set as a planar side wall Side walls or curved side walls. As another embodiment, the outer side wall 322 of the tangential air duct 320 can be set as a curved side wall, which is tangent to the side of the cylindrical cylinder 311 of the cyclone separation cylinder 310, and the inner side wall 323 is a flat side Wall or curved side walls.
进一步地,所述曲线通道330的入道口331对应所述切向风道320的切向出风口325,以减少不必要的回转路径,进一步降低压损。在某些实施例中,所述曲线通道330的出道口332对应所述圆柱筒311与倒锥筒312的连接处313设置,在另一些实施例中,所述曲线通道330的出道口332还可以对应所述倒锥筒312上部设置。如此设置之后,所述回转气流从所述出道口332出来后可直接进入到所述倒锥筒312。Further, the inlet 331 of the curved channel 330 corresponds to the tangential air outlet 325 of the tangential air duct 320, so as to reduce unnecessary turning paths and further reduce pressure loss.

It can be understood that the diversion inclined wall 341 corresponds to The extension surface of the upper wall of the tangential air duct 320 is arranged, and is designed in such a way that the air flow of the rotating airflow passing through the tangential air duct 320 is prevented from being formed by the rotation of the upper end cylinder wall of the cylindrical cylinder 311 through the guide inclined wall 341 . The "upper gray ring" not only causes energy loss, but also greatly interferes with the separation effect. Preferably, the diversion inclined wall 341 is arranged on the upper part of the outer wall of the overflow cylinder 340. For the convenience of manufacture, the diversion inclined wall 341 is circumferentially extended to form a diversion inverted frustum 342, as shown in FIGS. 12 and 13 . Show. Specifically, an obtuse angle is formed between the guide inclined wall 341 and the outer wall of the overflow tube 340 , which helps to guide the revolving airflow downward into the curved channel 330 . In some embodiments, the curved channel 330 and the guide inclined wall 341 are both disposed on the outer wall of the overflow cylinder 340 as an example, and the upper end of the curved channel 330 is connected to the guide reverse frustum 342, such as The upper end of the inlet 331 of the groove-shaped channel 333 or the head of the single-ended helical rib 334 or the head of the uppermost helical rib 334 of the multi-ended single-helix helical rib 334 is connected to the flow-guiding inverted cone 342 . In some preferred embodiments, the connection point 313 of the curved channel 330 and the flow-guiding inverted frustum 342 is located in the extension area of the tangential air channel 320, so as to avoid or reduce the existence of the "upper gray ring", At the same time, it also reduces the escape of unseparated swirling air flow, and also helps to guide the swirling air flow down into the curved channel 330 .

In some preferred embodiments, the bottom of the spoiler rib 343 does not extend to the bottom of the overflow tube 340 to prevent the spoiler rib 343 from interfering with the airflow that does not enter the overflow tube 340 . The airflow not only does not become straight and discharged quickly, but flows in other directions to affect the separation effect, and does not affect the air inlet space at the bottom of the overflow cylinder 340, ensuring that the inner swirling airflow smoothly enters the bottom of the overflow cylinder 340 and passes through the prolate shape. The spoiler ribs 343 interfere with the quick discharge after straightening.
所述溢流筒340底部延伸至所述旋风分离筒310的倒锥筒312的上部。可以理解的是,所述溢流筒340底部位于所述圆柱筒311与倒锥筒312的连接处313,或位于该连接处313的下方。本实施例优选所述溢流筒340底部延伸入所述倒锥筒312,位于其上部内。在某些优选实施例中,所述溢流筒340长度为所述旋风分离筒310长度的0.3~0.4倍,但不局限于此。其中,所述溢流筒340的长度理解为导流倒锥台342至溢流筒340底部之间的距离,或者是与所述切向风道320上壁平齐处起至溢流筒340底部之间的距离。The bottom of the overflow cylinder 340 extends to the upper part of the inverted cone 312 of the cyclone separation cylinder 310 . It can be understood that the bottom of the overflow tube 340 is located at the connection 313 of the cylindrical tube 311 and the inverted cone 312 , or is located below the connection 313 . In this embodiment, preferably, the bottom of the overflow cylinder 340 extends into the inverted cone 312 and is located in the upper part thereof. In some preferred embodiments, the length of the overflow drum 340 is 0.3-0.4 times the length of the cyclone separation drum 310, but not limited thereto. Wherein, the length of the overflow tube 340 is understood as the distance between the reverse conical frustum 342 of the flow guide and the bottom of the overflow tube 340 , or the length of the overflow tube 340 from the position flush with the upper wall of the tangential air duct 320 to the overflow tube 340 distance between bottoms.
请参考图6,所述溢流筒340上部设置有定位部344,以使得所述曲线通道330与所述切向风道320对应连通。通过所述定位部344的设计,在装配所述溢流筒340时,可以快速定位且定位后保证所述曲线通道330与所述切向风道320对应连通,降低装配难度以及提升装配精度。可以理解的是,所述定位部344可以与所述圆柱筒311进行配合设计,如所述定位部344被设置为一卡扣,装配时通过卡扣扣在预先设定在所述圆柱筒311筒壁外的盲孔231,但并不局限于此。Referring to FIG. 6 , a positioning portion 344 is disposed on the upper portion of the overflow tube 340 , so that the curved channel 330 is communicated with the tangential air channel 320 correspondingly. Through the design of the positioning portion 344 , when assembling the overflow tube 340 , it can be quickly positioned and positioned to ensure that the curved channel 330 and the tangential air channel 320 are connected correspondingly, thereby reducing assembly difficulty and improving assembly accuracy. It can be understood that the positioning portion 344 can be designed to cooperate with the cylindrical barrel 311 . For example, the positioning portion 344 is configured as a snap, which is pre-set on the cylindrical barrel 311 through the snap during assembly. The blind hole 231 outside the cylinder wall is not limited to this.
应当认识到,所述切向风道320可与所述旋风分离筒310一体成型,所述曲线通道330与所述溢流筒340一体成型,所述导流倒锥台342、定位部344也与所述溢流筒340一体成型,如此设计使得所述旋风分离器300容易制造和组装。It should be appreciated that the tangential air duct 320 can be integrally formed with the cyclone separation cylinder 310 , the curved passage 330 and the overflow cylinder 340 can be integrally formed, the flow guide reverse cone 342 and the positioning portion 344 are also integrally formed. It is integrally formed with the overflow cylinder 340, so that the cyclone separator 300 is easy to manufacture and assemble.
作为旋风分离器300排布的一种实施方式,所述多个旋风分离器300可以环状排布设置为一组旋风器环220。所述旋风器环220中的旋风分离器300沿所述旋风分离装置的旋风器支架210的环壁211周向排布。在某些实施例中,所述旋风分离器300的切向风道320贴着所述旋风器支架210环壁211设置,优选地,所述旋风器支架210环壁211作为所述切向风道320的外侧壁322。通过如此结构设计,从与所述下游旋风分离组件200连通的上游旋风分离组件100分离出来的气流,主要是沿着所述旋风器支架210环壁211向下游流动,从引风口400(所述引风口400为所述导风路径的下游出口)出来后可直接转向进入所述切向风道320,减少气流的移动路径,降低能量损耗。在某些实施例中,所述旋风分离器300的切向风道320不贴着所述旋风器支架210环壁211设置,可以理解的是,所述切向风道320的进风口326远离与所述旋风器支架210环壁211设置。As an embodiment of the arrangement of the cyclone separators 300 , the plurality of cyclone separators 300 may be arranged as a set of cyclone rings 220 in an annular arrangement. The cyclone separators 300 in the cyclone ring 220 are circumferentially arranged along the ring wall 211 of the cyclone support 210 of the cyclone separation device. In some embodiments, the tangential air duct 320 of the cyclone separator 300 is disposed against the annular wall 211 of the cyclone bracket 210 , preferably, the annular wall 211 of the cyclone bracket 210 serves as the tangential wind Outer sidewall 322 of channel 320 . Through such a structural design, the airflow separated from the upstream cyclone separation assembly 100 communicating with the downstream cyclone separation assembly 200 mainly flows downstream along the annular wall 211 of the cyclone support 210, The air inlet 400 is the downstream outlet of the air guiding path) and can be directly turned into the tangential air duct 320 after exiting, thereby reducing the movement path of the airflow and reducing energy loss. In some embodiments, the tangential air duct 320 of the cyclone separator 300 is not disposed against the annular wall 211 of the cyclone support 210 , and it can be understood that the air inlet 326 of the tangential air duct 320 is far away from A ring wall 211 is provided with the cyclone bracket 210 .
其中一种实施方式,请参考图15,同一所述旋风器环220的每一所述旋风分离器300可以均对应一个引风口400,即一个切向风道320对应一个引风口400,且引风口400区域除了所述切向风道320外均无遮挡,以加大进风量;同时一一对应,可避免多路气流发生对撞,形成紊流现象,出现紊流主要会造成气流回转效率低,进而不利于灰尘微粒从气流中分离出来。其中另一种实施方式,同一所述旋风器环220的两个所述旋风分离器300可以对应一个引风口400,即一个引风口400对应两个所述切向风道320,且引风口400区域除了所述切向风道320外均无遮挡,以加大进风量。进一步地,所述切向风道320的进风口326前侧的区域不遮挡,即气流从引风口400处一次转向即可进入所述进风口326,避免气流从引风口400进来之后进行二次转向再进入所述进风口326,减少气流不必要的移动路径造成能量损耗。In one embodiment, please refer to FIG. 15 , each cyclone separator 300 of the same cyclone ring 220 may correspond to one air inlet 400 , that is, one tangential air duct 320 corresponds to one air inlet 400 , and The area of the air outlet 400 is not blocked except the tangential air duct 320 to increase the air intake; at the same time, the one-to-one correspondence can avoid the collision of multiple airflows and the formation of turbulent flow. The turbulent flow will mainly cause the airflow rotation efficiency low, which in turn is not conducive to the separation of dust particles from the airflow. In another embodiment, the two cyclones 300 of the same cyclone ring 220 may correspond to one air inlet 400, that is, one air inlet 400 corresponds to two tangential air ducts 320, and the air inlet 400 Except for the tangential air duct 320, the area is not blocked, so as to increase the air intake volume. Further, the area on the front side of the air inlet 326 of the tangential air duct 320 is not blocked, that is, the airflow can enter the air inlet 326 after one turn from the air inlet 400, so as to prevent the air from entering the air inlet 400 for a second time. Turning and re-entering the air inlet 326 reduces the energy loss caused by the unnecessary movement of the airflow.
作为旋风分离器300排布的另一种实施方式,所述多个旋风分离器300可以彼此并联地设置为多组旋风器环220,每组旋风器环220的所述多个旋风分离器300周向排布为环状,相邻组的旋风器环220相互嵌套或局部嵌入同心圆设置。以两组旋风器环220为例,第一组旋风器环220具有较多的数量,形成相对较大的环状旋风器环220,第二组旋风器环220被部分的接入或嵌入所述第一组旋风器环220中,可以理解为,俯视状态下,所述第一组旋风器环220将第二组旋风器环220环绕在里面,不同组旋风器环220的高度可根据实际情况设计为相同或不同,为了进一步结构优化,避免增大所述旋风分离装置的体积,优选地,较小环状的环状旋风器环220插入到较大环状的环状旋风器环220的内环,以形成在轴向上较小环状堆叠在较大环状的上方,且较小环状的外环与较大环状的内环部分接触或靠近。As another embodiment of the arrangement of the cyclone separators 300 , the plurality of cyclone separators 300 may be arranged in parallel with each other as a plurality of sets of cyclone rings 220 , and the plurality of cyclone separators 300 in each set of cyclone rings 220 The circumferential arrangement is annular, and adjacent groups of cyclone rings 220 are nested with each other or partially embedded in concentric circles. Taking two groups of cyclone rings 220 as an example, the first group of cyclone rings 220 has a larger number to form a relatively large annular cyclone ring 220, and the second group of cyclone rings 220 is partially connected or embedded. In the first group of cyclone rings 220, it can be understood that, in the top view state, the first group of cyclone rings 220 surrounds the second group of cyclone rings 220, and the heights of different groups of cyclone rings 220 can be determined according to actual conditions. The situation is designed to be the same or different, in order to further optimize the structure and avoid increasing the volume of the cyclone separation device, preferably, the smaller annular annular cyclone ring 220 is inserted into the larger annular annular cyclone ring 220 The inner ring is formed so that the smaller ring is stacked above the larger ring in the axial direction, and the outer ring of the smaller ring is partially in contact with or close to the inner ring of the larger ring.
需要说明的是,多个旋风分离器300的作用是在一定的平面内,旋风分离分离器300数量越多,分离器300的半径就越小,根据向心力公式F=M*V²/R 公式可知,半径越小,向心力越大,向心力越大,气流中各种不同质量的物质的分离效果就越好。It should be noted that the function of multiple cyclone separators 300 is in a certain plane. The more the number of cyclone separators 300 is, the smaller the radius of the separators 300 is. According to the centripetal force formula F=M*V²/R formula , the smaller the radius, the greater the centripetal force, the greater the centripetal force, the better the separation effect of various substances of different masses in the airflow.
优选但不限定地,所述旋风分离筒310的轴线350相对所述旋风分离装置的纵向中轴线500倾斜设置。值得注意的是,同组的旋风器环220中不是所有的旋风分离器300都需要相对于所述旋风分离装置的纵向中轴线500倾斜相同的角度,即同组的旋风器环220中的旋风分离器300相对所述旋风分离装置的纵向中轴线500倾斜角度可不相同。类似的,同组的旋风器环220中不是所有的旋风分离器300都需要具有相同的内部尺寸。Preferably, but not limitedly, the axis 350 of the cyclone separation drum 310 is inclined relative to the longitudinal center axis 500 of the cyclone separation device. It is worth noting that not all cyclones 300 in the same group of cyclone rings 220 need to be inclined at the same angle with respect to the longitudinal center axis 500 of the cyclone separation device, that is, the cyclones in the same group of cyclone rings 220 The angle of inclination of the separator 300 with respect to the longitudinal center axis 500 of the cyclone separation device may be different. Similarly, not all cyclones 300 in the same set of cyclone rings 220 need to have the same internal dimensions.
请参考17-19,所述下游旋风分离组件200还包括密封件230,其设置在所述旋风器环220的上方。为了便于所述下游旋风分离组件200的装配及进一步简化结构和减轻所述旋风分离装置,所述切向风道320的上端是敞口设置的,旋风器支架210上端也是敞口设置的,装配时,所述密封件230压设在所述旋风器环220的上方,即至少密封所述切向风道320上端、引风口400上端。优选地,所述密封件230还设置多个孔231,其密封抵接在所述溢流筒340外侧,可以理解的是,所述密封件230开孔231以避让所述溢流筒340之外,均将所述旋风器环220其余部分密封住。Please refer to 17-19, the downstream cyclone separation assembly 200 further includes a sealing member 230 disposed above the cyclone ring 220 . In order to facilitate the assembly of the downstream cyclone separation assembly 200 and further simplify the structure and lighten the cyclone separation device, the upper end of the tangential air duct 320 is open and the upper end of the cyclone bracket 210 is also open. At the time, the sealing member 230 is pressed and arranged above the cyclone ring 220 , that is, at least the upper end of the tangential air duct 320 and the upper end of the air inlet 400 are sealed.
